Wario is a recurring character in the Mario franchise. He is an obese, muscular, hot-tempered, and greedy man, and Mario's yellow-and-purple clad arch-rival. He usually appears as an anti-hero, or in some cases an antagonist. His name is a combination of Mario's name and the Japanese word warui (悪い), meaning "bad".
Wario's greed pushes him to commit malevolent acts, such as the seizing of Mario's castle. Wario has also proven to be very cunning as he has tricked Mario on many occasions. He often goes out on his own adventures, from stealing treasure to running a microgame making company. Wario has helped heroes of the Mushroom Kingdom on a few separate occasions as well.
